OSCILLATORY WAVE FORCES ON A VERTICAL CIRCULAR CYLINDER INCLUDING VISCOUS EFFECTS

A study is made of the oscillatory flow of a viscous incompressible fluid with a free surface, in the presence of a fixed vertical circular cylinder. An expression is derived for the oscillatory wave-induced force on the cylinder. The analysis is based on the linearized equations of motion for the fluid, invoking the small wave amplitude assumption, but including the viscous terms. The results are compared with the inviscid solution by Havelock, and the solution for an oscillating cylinder in an infinite viscous fluid obtained by Stokes, showing the combined effects of the inviscid drag force due to the reflected wave and viscous drag force.
